Donaldson® Endurance™

Donaldson Endurance air and oil filters provide the highest level of filtration efficiency in the heavy-duty industry. Specifically designed for onroad, heavy-duty class 6, 7 and 8 vehicles, Donaldson Endurance air and oil filters feature revolutionary nanofiber technology.

Endurance air filters offer longer engine life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity than conventional cellulose filters.

Endurance air filters come with a “twice the miles” guarantee to deliver twice the miles between change intervals over cellulose air filters for onhighway applications, or customers receive a new filter at no charge.

Donaldson Endurance oil filters are made with advanced synthetic technology that results in fibers that have a controlled size, down to submicron diameters.

This controlled process allows Endurance oil filters to deliver both higher dirt holding capacity at the same pressure differential and higher efficiency compared to conventional cellulose filters. The synthetic media also has better durability and increased resistance to water.

Donaldson P-Series

AMSOIL also offers filtration products from Donaldson’s P-Series line. With many applications that differ from, and several that coincide with the Endurance line, Donaldson P-Series filters offer premium filtration at a competitive price. Donaldson P-Series filters feature housing constructed with heavy gauge steel and domed construction, providing superior pressure fatigue performance. Donaldson P-Series oil filters are constructed with either full synthetic media or synthetic blends for high efficiency. The center tube allows more flow without compromising strength, and the louvered design eliminates tearing during pleat movement.
